C&L's require that you still have the stock MAF sensor electronics. I had to go to a used parts store to get one. It was $25. We're only talking about a couple mm here and if you don't plan to change injector size, the 75mm bullet should be fine for you. The nice thing about the C&L 76mm that I got is that you can recalibrate it for a lot less than the Pro-M and you can get it as part of a kit with that great intake pipe for about $200. It's a real tight fit to get that intake pipe installed. Some "finessing" of the strut tower may be necessary to get it to fit easily. Use Ford special tool #H-32588 below:
